Constant time binomial and poisson generation #229

Closed molpopgen closed 4 years ago

molpopgen commented 4 years ago

With tree sequence recording + large genomic intervals, one starts to notice gsl_ran_poisson in the profiles. The genetic map classes should use constant time generators for these distributions.

Note: this will change results for the same seed. Need to decide if we simply update existing classes or add new ones. Either way, fwdpy11 is affected.

Some testing reveals that this won't help much in practice.
